ipython
import Image
im = Image.open('20090201-1601-with-exif-gps.jpeg')

In [29]: im._getexif()

KeyError                                  Traceback (most recent call last)

/sw/lib/python2.6/site-packages/PIL/JpegImagePlugin.pyc in _getexif(self)
    352             exif[key] = fixup(value)
    353         # get exif extension

--> 354         file.seek(exif[0x8769])
    355         info = TiffImagePlugin.ImageFileDirectory(head)
    356         info.load(file)

KeyError: 34665

However, jhead works...
